I have 10 50watt 120v leds was wondering if I could run them off my 4705 watt genny? I don't know much about electrical work. I need all the help that I can get thanks guys.

If you are only running the LEDs off the genny then that 4705w genny is way overkill and is nothing but added weight in the boat. You're only talking about pulling 500w (10x50w) at 4.1666 amps ([50w/120v]x10)

You could run a 24v converter (depending on amperage needed) or two 12v converters. Your cranking battery doesn't need a converter. Contact Gbollum on here, he can give you the run down on what converter setup you will need and you can also purchase Powermax converters through him.

To figure out what size generator would fit you're setup use this formula...

For example I run (7) 300w Halos and a 55amp powermax in my boat. So take (7x300w) [lights] + 750w [converter] = 2850w. Based off these number I run a 3500/4000 watt champion generator. As a rule of thumb you don't want to go over 80% of the running watts on the generator. So in my case 80% of 3500 is 2800 so I'm only 50w over 80% which isn't to big of deal, it's a little under 82%.

Edit: You also need to keep track of the amp draw on your system to make sure your generator can handle the amp load of your setup.

Just need to get out the crayon.

Yes, it will run them fine, 10 50 watt lights is 500 watts. you have a 4700 watt genny, that leaves you 4200 watts left over to run? table saw? Blender? an entire kitchen?

haha, all in fun.

as to the converter, you dont need it to run your lights, the lights are already 120V. A converter is only if you want to charge your batteries with your generator. which seeing how much genny you are going to be running is a really good idea.

You do the right by asking advice. I was thrust into vo tech by my parents. I ended up taking basic electronics several times. Just as stated: AMPS X VOLTS = WATTS. WATTS / VOLTS = AMPS. There are ampacity charts for different wires. AC wires are usually only amp rated. This is because the runs in a home are short. If your genny has a ckt breaker on it, then it is protected only from a short. Run your genny at amps 20% less than it is rated, and it will do fine. A ground fault will save your na nan. You see it only takes 50 mili amps of 120 V to kill.
